ABSTRACT

A device for locally shielding or blocking a user from close proximity electromagnetic fields emitted by a wireless transmit/receive electronic equipment antenna  22  such as a cellular telephone. The device includes a wearable garments such as a baseball cap  10,  electronic carrying pouch  110,  fan  210, 250, 410,  eyeglass  610 , or screens, joined with having EMI/RFI material properties that is specifically worn by the user or placed between the user and the electromagnetic field emanating wireless antenna source  22.  It serves to provide as a electromagnetic field shield, either reflective, absorptive, or dissipative behavior in nature, from an direct line-of-sight electromagnetic field radiating from a wireless device antenna  22.  The effective shielding area is determined by the shielding device dimensions, the direct line-of-sight electromagnetic field signal antenna transmission behavior and the placement of the shielding device located between the user local human body sensitive tissue area and the wireless transmit/receive electronic equipment antenna  22,  as solutions for opened-form design method shielding which serves to minimize the shielding degradation effects and sensitivity interaction effects on normal non-blocked electromagnetic fields antenna signal transmission operation.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] This invention relates generally to shielding electromagneticinterference/radio frequency interference (EMI/RFI) fields and, moreparticularly, to shielding sensitive local human body tissue parts frompotential harmful electromagnetic fields emanating from close proximitydirect line-of-sight wireless transmit/receive electronic equipmentantenna source.

[0004] 2. Description of the Related Art

[0005] There is much concern throughout the world that electromagneticfield radiation and microwave radiation may cause human body tissuedamage. The antenna and the body of wireless transmit/receive electronicequipment such as a cellular telephone and higher frequency bandtransceivers come in close contact with a person head or sensitive humanbody tissue part thereby creating a close exposure to electromagneticfield and microwave radiation. Because of these hazards and to offersome protection against these hazards, some form of shielding deviceswere invented. Current state-of-the-art provide accessories for cellulartelephones or higher frequency band transceivers that will afford someprotection to cellular telephone and higher frequency band transceiverusers from the alleged brain, head and sensitive body tissue damagecaused by electromagnetic field radiation of cellular telephone orhigher frequency band transceiver use. These accessories are primarilyof closed-form design solutions around the electronic equipment toreduce electromagnetic field radiation emanating from the electronicequipment body, but does not attempt to sufficiently reduceelectromagnetic field radiation from the antenna, regarding directline-of-sight signal transmission between the antenna and the sensitivehuman body tissue part without causing serious impact to normal signaltransmission operation.

[0006] Some attempts to implement closed-form method shielding designsolutions around electromagnetic field radiation from an electronicequipment antenna would be very difficult to implement without causingtremendous antenna transmit/receive signal degradation for the equipmentand still be effective in providing sufficiently adequate shielding forthe user. Strict and exacting design parameters and controls over timeof equipment operation on shield spacings, positioning, shield partdimensions and material electrical characteristic behavior parametersunder normal stress movement conditions by the user, would be requiredto solve the complex and specific antenna electromagnetic fieldfrequency response voltage standing wave ratio loading and matchingcriteria relative to that particular antenna electrical structure designin order for proper antenna operation.

[0007] Note that for added clarification regarding the concept ofclosed-form method design solutions, a simplified circuit model is shownin FIG. 11, that shows a comparison between the closed-form versusopened-form method design solutions as applied to close-proximityelectromagnetic field radiation exposure to the user. Also note that thebasic distinction for the closed-form method design solutions is for theshielding to encompass around the electronic equipment body or antennaas noted by the diagrammed reference node point to antenna. But withregards to the opened-form method design solution, is the shielding toencompass around the human body user part as noted by the diagrammedreference node point to user. Further note, if we were to start with thesame finite small closed-form and opened-form surface shielding area andnow increase each surface area evenly further, the closed-form shieldingarea encompasses and terminates more electromagnetic fields from theantenna thereby increasing the design sensitivities and interactions,whereas for the opened-form shielding area does not encompass orterminate electromagnetic fields appreciably to affect the antennaoperation any further for matters that would be appreciated by thoseskilled in the art.

[0008] What is needed is an opened-form method design solution that issimply detached from the design requirement of solving for complexantenna matching criteria parameters and now centered the designsolution around the exposed electronic user body part, serving means toprovide an electromagnetic field radiation shielding or blockage, eitherreflective or absorptive or dissipative behavior in nature, in order toreduce the direct line-of-sight antenna electromagnetic field radiationto the sensitive human body tissue part without causing significantantenna signal transmit/receive degradation for proper wirelesselectronic equipment operation and simplifying the shielding devicedesign, irrespective of any antenna strict electrical and structurematching criteria that would be imposed if one were to use parametersfor closed-form method design solutions, thus simplifying the presentinvention fabrication, improving performance reliability andrepeatability of the present invention.
